|
function of respiratory |
to privide oxygen to cells |
|
|
what are the four processes of respiratory |
pulm ventilation external respiration transport of gases internal respirtation |
|
|
pulmonary ventilation |
breathing in and out |
|
|
external respiration |
gas exchange between lungs and blood |
|
|
transport of gases |
blood hemoglobin brings oxygen from lungs to tissues |
|
|
internal respiration |
exchange of gases at cap bed in cells (diffusion) |
|
|
organs of respiratory |
nose sniuses pharynx larynx rachea lungs |
|
|
nose |
nares, conchae, sinuses, hard and soft palate (warm, moisten and filter air( |
|
|
pharynx |
nasopharynx oropharynx larygopharynx
|
|
|
larynx |
voicebox 9 cartilages thyroid and cricoid cartilage epiglottis |
|
|
thryoid |
hylane. shield shaped |
|
|
cricoid |
hylaine ring shaped |
|
|
epiglottis |
elastic, covers larynx during swallowing |
|
|
respiratory mucosa consits of |
epithelial membrane-mucus secreting ciliated epithelium underlying areolar layer called lamina propria
WARM MOISTEN FILTER |
|
|
trachea |
11 cm in length extends to t5 lined with muscus secreting ciliated epithelium propel dust, bacteria and other objects back to throat for expulsion
c shaped cartliage- open in back toward esophagus to allow expansion for swallowing large food particles |
|
|
bronchi |
right- 3 lobes shorter wider, vertical left- 2 lobes, cardiac notch |
|
|
viscereal pluera |
inner layer, covering lung |
|
|
parietal pluera |
outer layer, attaches to throacic wall and diaphram |
|
|
plueral fluid |
decrease friction surface tension allows lungs to expand |
|
|
bronchi tree |
right/left primary secondary teritary bronchioles respiartory aveloar ducts
more cartliage at top- pressure smooth muscle to allow for control and diameter |
|
|
conducting zone |
nasal to terminal bronchioles |
|
|
respiartory zone |
respiartory bronch and aveloli |
|
|
alveoli |
air filled pockets within lungs where all gas exchange takes place |
|
|
respiratory zone |
respiratory bronchioles become alveolar ducts alvelor sacs (clucsters( like ballon- expansions along sac single layer of epithelial cells and then layer of connective tissue |
|
|
respiratory membrane |
alevolar wall cap wall fused basement membranee simple diffusion |
|
|
asthma |
irritation and inflammation of bronchal passages
bronchiol constriction and mucus roduction |
|
|
COPD |
chronic bronchitis and ephysemea structural damage of alveolar sacs inhibits gas exchange loss of elasticity trapping of co2 |
|
|
lung collapse |
elasticity of tissue surface tension of alevolar fluid
negative pressure diffferential from pluera surfactant |
|
|
pneumothorax |
trauma to chest wall disrupts suction effects of transpulmonary pressure causing lung to collapse
- air in space hemothroax- blood in plueral space plueral effusion-pleural fluid |
